Proposed rule

Airworthiness Directives; Airbus Helicopters Deutschland GmbH (AHD) Helicopters

Built by the Tribune's code from the Federal Register. No AI wrote this page. Published in the Federal Register June 29, 2026. Document 2026-13034. Updated Nov. 9, 2026.

What it does

The FAA proposes to adopt a new airworthiness directive (AD) for all Airbus Helicopters Deutschland GmbH (AHD) Model EC135P1, EC135P2, EC135P2+, EC135P3, EC135T1, EC135T2, EC135T2+, EC135T3, and EC635T2+ helicopters. This proposed AD was prompted by a report of a separated tail rotor blade (TRB) assembly due to a crack caused by intergranular corrosion. This proposed AD would require repetitively inspecting a certain TRB assembly for cracks and, depending on the results, removing any cracked TRB assembly from service and replacing an affected part as terminating action for the repetitive inspections. This proposed AD would also prohibit installing a certain TRB assembly on any helicopter unless certain requirements are met. The FAA is proposing this AD to address the unsafe condition on these products.
